Definitions

  • the invention relates to a motor vehicle with an air conditioning system according to the preamble of patent claim 1.
  • Compression systems which contain fluorocarbons or chlorofluorocarbons as the circulating medium have hitherto been used to air-condition the passenger compartment of motor vehicles. From the point of view of environmental compatibility, the search for alternative media that make little or no contribution to a greenhouse effect is becoming increasingly important.
  • a compression system with CO2 as a circulating medium is inexpensive and environmentally neutral. Due to the high vapor pressures of CO2, a different system technology and more pressure-resistant system components is required compared to the previous systems. Such systems are known for example from WO 90/07683. In traffic accidents, however, due to the high pressure level of CO2 in the circuit of the air conditioning system when damaged, an uncontrolled leakage of CO2 can occur, which can lead to health risks, in particular for the vehicle occupants.
  • fire extinguishing systems for the motor vehicle are provided, as are known, for example, from DE-GM 87 15 208.8.
  • the extinguishing system contains an extinguishing agent container and extinguishing lines, which are brought to potentially fire-prone places in the engine compartment. If necessary, they are deleted using crash or temperature sensors, but can also be triggered manually. A special sensor system for this is detailed in EP-OS 487 445 removable.
  • Such extinguishing agent systems represent a considerable additional weight for the total weight of the vehicle, which is associated with increased fuel consumption.
  • the extinguishing agent container takes up additional installation space, which is insufficient to accommodate such an extinguishing system, particularly in small cars.
  • the invention has for its object to develop a generic motor vehicle in such a way that a hazard to the occupants is avoided by a developing fire in a vehicle crash.
  • the invention uses the circuit medium of the air conditioning system as a fire extinguishing agent or the air conditioning system as a fire extinguisher dispenser in a simple manner in a space-saving manner, with a separate extinguishing agent store being dispensed with.
  • the extinguishing agent lines and the nozzles which end at the possible sources of fire, represent only an insignificant additional weight for the vehicle.
  • an automatic fire extinguishing process is carried out via a sensor system Fire is involved and supports the kindled fire, displaced to the areas at risk of fire.
  • a controlled outlet of the circulating medium is thus conceivable both preventively to avoid fire and fire injuries and actively to extinguish a fire that has arisen, so that overall a hazard to the vehicle occupants in the event of a fire is avoided.
  • a reservoir 2 which contains an environmentally friendly, non-flammable, non-toxic circuit medium 3 such as CO2 and is located on the low pressure side of a compressor 4 directly connected to it, driven by the vehicle engine.
  • Conceivable alternatives to CO2 as well as circulators of an air conditioning system that can be used as extinguishing agents are N2, SF6, N2O.
  • the compressor 4 is connected on its high-pressure side to a condenser 5 located in front of the engine cooler, which in turn is connected to an evaporator 6 connected to the reservoir 2 and arranged in the fan unit of the engine. Downstream of the condenser 5 and upstream of the evaporator 6, an expansion valve 7 is interposed in the circuit 1, through which the circulation medium is relaxed and cooled when it is passed to the evaporator 6.
  • the individual components 2, 4, 5, 6, 7 of the air conditioning system are connected to one another in the circuit 1 by pressure lines 8, from which fire extinguishing lines 9 branch off. These end at points of the engine compartment of the motor vehicle which are at risk of fire and have extinguishing nozzles 10 there.
  • Solenoid valves 11 are arranged in the fire extinguishing lines 9 and are connected to an electronic control unit 13 via control lines 12.
  • sensors 14 In control unit 13, electrical signals from sensors 14 are processed, by means of which certain or all solenoid valves 11 are activated in the event of a crash and / or fire.
  • the sensors 14 can be crash sensors which are expediently formed by the crash sensors for the airbag and / or belt tensioners or which are arranged separately from these. Furthermore, some of the sensors 14 can also consist of fire sensors which are arranged locally at certain possible sources of fire and act in the manner of temperature sensors.
  • Deformation sensors 15 can also be attached to the individual components of the air conditioning system, which react to damage to the air conditioning system by opening the extinguishing nozzles 10 via the control unit 13. Sensors are also conceivable which, for example, signal an excessive pressure in the circuit in the event of a fire or can detect a leak in the event of damage as a result of a pressure drop in the circuit and then possibly initiate an extinguishing process. Furthermore, a manually operable switch button 16 is provided, with which the vehicle occupant has the option of opening the valves 11 specifically.
  • the magnetic valves 11 are controlled by the sensors 14, 15 or the actuation of the switch button 16 or the deformation sensors 15 by the control unit 13, so that CO2 from the circuit 1 of the air conditioning system via the extinguishing lines 9 from the extinguishing nozzles 10 in a controlled and non-hazardous manner and can specifically extinguish the source of the fire or preventively ignite easily inflammable areas such as the injection and ignition system on the engine block.
  • the prerequisite is that the circulating medium of the air conditioning system can be extinguished like CO2.
  • the pressurized CO2 cycle of the air conditioning system is checked locally, relieved, the CO2 gases being passed into rooms in which they are harmless to the vehicle occupants, so that a risk of suffocation is avoided.
  • the air conditioning system is preferably emptied in such a way that atmospheric pressure is established in the circuit so that there is no risk of explosion if the air conditioning system is damaged.
  • valves which are formed here by the solenoid valves 11, which, when the overpressure is increased, are pressed open to release CO2.
  • extinguishing nozzles 10 can be provided with which areas of the motor vehicle can also be sprayed outside the engine compartment.
